- for CU310-2, CUA31 and CUA32 the undervoltage threshold is 16 V.
- for all other power units, the undervoltage threshold depends on the power unit, and is not displayed.
Fault value (r0949, interpret decimal):
24 V voltage [0.1 V].
Remedy:
- Check the power supply of the power unit.
- carry out a POWER ON (power off/on) for the component.
